I purchased a KUSB cable and downloaded the latest driver (v2.0.4.102) from the Prolific website, as directed on the Electraft website, for my K3. Although the Elecraft Utility program worked perfectly, and I found that full rig-control worked in Logger32 but with CPU running at 100% constantly. Obviously this was a problem as the pc slowed to a crawl. PC is 2.2 Ghz with 1.5Gb ram. Running other logging software (Wintest, HRD) was fine with no addition CPU loading. Only Logger32 displayed this 100% CPU payload. To further test, I installed the prolific usb-serial driver onto 2 other XP laptops. One was brand new out the box and all 3 had different Anti Virus packages. The exact same poor behaviour was found on both as on the original XP Home desktop. The resolution was to uninstall the USB-Serial driver and install an older Prolific driver (v2.0.2.8) which resolved the issue. Link below.

Thought I would share this in case it helps someone. 73's de Gordon MM0GPZ -- View this message in context: http://n2.nabble.com/KUSB-and-Logger32-tp1660775p1660775.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
